IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 108,757, dated November1, 1870.

To all whom it may concern Be it known that I, J OEL '1. CASE, of NewHartford, county of Litchfield and State of Connecticut, have inventedcertain new and useful Improvements in Water-Wheels; and to enableothers skilled in the art to make and use the same I will proceed todescribe, referring to the drawings, in which the same letters indicatelike parts in each of the figures.

The nature of this invention will be understood from the specificationand drawings.

In Figure 2, Sheet 2, is shown a side elevation of this improvement. OnSheet 1 is shown the various portions of this wheel, in detached parts.Fig. 3 is a top view of the case in which the wheel is arranged, and thechutes which conduct the water to the wheel. These chutes are formed inthree sectional portions, 1 2 3, each having four chutes, a b 0 cl. Eachsection occupies one sixth of the diameter of the case, Fig. 4 is anedge view of the case. Fig. 2 is a top view of the partially-rotatinggate, the rim of which covers the edge of the case, and is provided withthree openings corresponding with the sections in which the chutes arearranged, and are sufficiently large, so that, when over the ports ofthe chutes, they will allow a full flow of water, equal to thedimensions of the ports to the chutes, the supporting-rim f of which isprovided with a segment of gear for opening and closing the gate bymeans of an upright shaft, 2', and gear h. Fig. 5 is an edge view of thewheel proper, and its shaft. Fig. 1 is a spider secured to thewater-chute case, in which is arranged a step to support the lower endof the wheel-shaft. Fig. 6 is an under-side view of the wheel.

In Sheet 2, Figs. 2, 3, 4, is shown a double gate, which I propose touse sometimes, when it may be desirable to admit the flow of water to agreater number of chutes through the case.

A is the wheel proper. The top plate 13 is of one flat piece of metaL-The buckets are formed of two pieces of metal, 0 D. The piece 0 formsthe back and one end of the bucket. The piece D forms the bottom of thealternate bucket.

from the buckets, as indicated by darts. First, one bucket dischargesdirectly under the succeeding bucket, and the next discharges from itsinside edge toward its shaft, alternately first under one bucket, theninwardly back of the other, thus securing a free discharge of the waterfrom the wheel, and thereby prevent reaction friction upon the wheel.This wheel is secured to the shaft E, the lower end of which takes itsbearing in or on the step,

b 0 cl are formed. The ports of these chutes in each section 1 2 3occupy one-sixth of the diameter of the case. They are made in circularform from the outside to the inner edge of the case, or the point ofdischarge into the wheel. H is the gate, which partially rotates to openand close the ports to the case, the cylindrical rim of which covers theopenings or ports a b c d, the rim f of which is pro vided with asegmental gear, g, and, by means of a gear, h, secured on or near thelower end of the shaft i, the gate is opened and closed; or, in otherwords, by means of the shaft and gearing the gate is moved on the caseGr, so

that one, two, or more of the ports to the chutes will be opened atthree equal points around the wheel. By the use of the double gate, asshown on Sheet 2, Figs. 2, 3, 4, the wheel-case may be made withchutesoccupying, on two opposite sides of the case, about one-third ofthe diameter of the wheel-case, leaving between the chutes a space aboutonesixth of the diameter of the wheel-case to be occupied by the doublegate, when it is fully open. Thus one, two, or all of the ports to thechutes may be open, as desired, to allow the water to flow to the wheel.The two closing portions of this double gate, one part being actuated toopen or close by the action of the other, cover all the ports of thechutes. By turning or opening one portion full open, one-half of theports will be open, then, by turning it still further, this first partwill move the other portion, and when both ports are fully open andoccupy the space between the ports all the ports will be open. The gateis of water alternately under the wheel and from its inner edge,substantially as set forth.

2. The rotating gate H, in combination with the case G, constructed asset forth, with the shaft i, gear h, segment 9, as and for the purposeset forth.
